Item 1.01                     Entry into a Material Definitive Agreement.

On October 10, 2011 First Financial Corporation, an Indiana corporation (“First Financial”), entered into a Purchase and Assumption Agreement (the “Agreement”) with PNB Holding Co, an Illinois corporation (“PNB”).  Pursuant to the Agreement, First Financial will purchase from PNB all of the issued and outstanding stock of Freestar Bank, National Association, and assume certain liabilities of PNB (the “Transaction”).  First Financial anticipates that immediately following the acquisition of the stock of Freestar Bank, it will cause Freestar Bank to merge with and into its wholly-owned subsidiary, First Financial Bank, National Association.

The Agreement provides that First Financial will pay PNB cash in the amount of $47 million and assume certain liabilities of PNB in the aggregate amount of approximately $8.2 million.  The Transaction value may change due to fluctuations in the tangible book value of PNB.  If PNB’s tangible book value as of a date within five days of the closing is less than $28,431,000, the purchase price will decrease by an amount equal to 1.657 times the difference between PNB’s tangible book value and $28,431,000.  If PNB’s tangible book value as of a date within five days of the closing is greater than $28,987,000, the purchase price will increase by an amount equal to 1.657 times the difference between PNB’s tangible book value and $28,987,000.

PNB has agreed not to solicit proposals from any other person or entity relating to alternative business combination transactions or enter into discussions or negotiations with any other person or entity in connection with any proposals for alternative business combination transactions.  First Financial may terminate the Agreement if PNB breaches this covenant.  If First Financial terminates the Agreement for this reason and PNB subsequently enters into an acquisition transaction with such other person or entity, PNB has agreed to pay First Financial a termination fee in the amount of $470,000.  The Agreement provides certain other termination rights for both First Financial and PNB.

The Agreement contains representations, warranties, and covenants of First Financial and PNB, including, among others, a covenant that requires (i) PNB to conduct its business in the ordinary course during the period between the execution of the Agreement and the effective time of the Transaction, and (ii) PNB not to engage in certain kinds of transactions during such period without the prior written consent of First Financial.

The Agreement has been approved by the boards of directors of First Financial and PNB.  The Agreement requires First Financial and PNB to use their reasonable best efforts to close the Transaction on or before December 31, 2011.   The Transaction also is subject to various conditions, including (i) receipt of the requisite approval of the shareholders of PNB, (ii) receipt of regulatory approvals, (iii) absence of any litigation which might reasonably be expected to materially and adversely affect the Transaction or materially and adversely affect the business of Freestar Bank.  In addition, each party’s obligation to consummate the Transaction is subject to certain other conditions, including the accuracy of the representations and warranties of the other party and compliance of the other party with its covenants in all material respects.

The representations, warranties and covenants contained in the Agreement were made only for purposes of the Agreement and as of specific dates, were solely for the benefit of the parties to

the Agreement, and are subject to limitations agreed upon by the contracting parties, including being qualified by confidential disclosures exchanged between the parties in connection with the execution of the Agreement. The representations and warranties may have been made for the purposes of allocating contractual risk between the parties to the Agreement instead of establishing these matters as facts, and may be subject to standards of materiality applicable to the contracting parties that differ from those applicable to investors. Investors are not third-party beneficiaries under the Agreement and should not rely on the representations, warranties and covenants or any descriptions thereof as characterizations of the actual state of facts or condition of First Financial or PNB, or any of their respective subsidiaries or affiliates. Moreover, information concerning the subject matter of the representations and warranties may change after the date of the Agreement, which subsequent information may or may not be fully reflected in First Financial’s or PNB’s respective public disclosures.

The foregoing description of the Agreement is not complete and is qualified in its entirety by reference to the full text of the Agreement, which is filed as Exhibit 2.1 hereto and is incorporated herein by reference.

Pursuant to General Instruction F to Form 8-K, a press release issued jointly by First Financial and PNB is attached hereto as Exhibit 99.1 and is incorporated herein by reference.
